Answer
This is not a solution to the equation.
Work Step by Step
In order to see if something is a solution to an equation, we plug in the (x,y) point to see if the equality is correct. Thus, we plug (-6,0) into $y=-2(x+3)$ to find:
$0=-2(-6+3)$
$0=-2(-3)$
$0=6$
6 does not equal 0, so this is not a solution to the equation.
